Today out of nowhere.. my game has started crashing after only a few minutes in game. It's happened 4 or 5 times in a row now. Once it even kicked me to a BSOD. I've made no changes to my system since it last worked. I get no error message of any kind. Just a black screen and i need to start task manager to get out of it.

Video card drivers are up to date. Restarted a couple of times. Closed other programs. Verified game files in steam.
